Chirp filter
WebThe up-chirp (UC) LFM waveform is known to give better radar tracking than a monotone waveform or a down-chirp LFM waveform. However, the question of the value of other LFM waveforms to tracking is raised. In this paper, the value of an up-chirp-down-chirp (UCDC) waveform to radar tracking is considered. The optimal steady-state filter for tracking a … WebJun 22, 1991 · Abstract. The complete computer-aided design procedure for surface acoustic wave (SAW) chirp filters with interdigital transducers (IDTs) is considered. In the design, the single dispersive ...
